3- Make sure that the md5 checksum of your iATKOS iso image matches the one posted on our website or the one in md5.rtf file. Otherwise you may have a faulty DVD image. Use quality media/burner and burn slowly.

- The major improvement on this 5i release is updating your running system using software updater just like real Macs. This is possible for Intel based chipsets. Please read the information about preparing an upgradable system.

- Main system is fully stock! That means it can't run on x86 hardware without selecting none of x86 patches. At least you need to choose one of the decrypters.

Attention! iATKOS 5i 10.5.5 Intel DVD has been released at November 29, 2008.

Release Information This DVD is designed for Intel architectures.

Minimum requirements: Intel SSE2 CPU, 512MB RAM, 10GB free space on target partition, OpenGL VGA card. Recommended: Intel Core CPU, 1GB RAM, 15GB free space on target partition, nVidia 6xxx or newer - ATI X1300 or newer - Intel GMA950 or X3100 VGA card. This DVD includes Apple's Mac OS X Leopard 10.5.5 (9F33) installation. Make sure that the md5 checksum of your iATKOS iso image matches the one posted on our website. Otherwise you may have a faulty DVD image. Use quality media/burner and burn slowly. This OSX86 installation DVD release supports both GPT and MBR partitioned harddrives. The major improvement on this 5i release is updating your running system using software updater just like real Macs. This is possible for Intel based chipsets. Please read the information about preparing an upgradable system below. Main system is fully stock! That means it can't run on x86 hardware without selecting none of x86 patches. At least you need to choose one of the decrypters.

Installation Run Disk Utility via Utilities menu and erase the target partition for clean install. Do partitioning if you need to.

a - You can choose MBR (Master Boot Record) or GPT (Guid Partition Table) via partitioning options. If you want to change your existing partition table type, note that all your existing data on disk will be gone. b - For Windows fellows that has not tested this amazing system yet and that does not want to loose their windows software, porn and virus&trojan archive on D:, should use Parted Magic Live CD for preparing an active primary target partition and after that, just erase it via diskutil. Jump to Step 2.

1. Select the destination for installation.

2. Click *Customize* and select what you need.

3. Click Install.

Install time is about 20 minutes.

The Customize section is the most important part of the installation for you to make OS X work on your hardware. iATKOS Main system: If you want to install the osx86 main system, you need to select this. Bootloader: You have 2 choices. You must select one of them for booting your osx86 system. PC_EFI V9 is an "all in one" bootloader and has many options. The most important ones are DSDT override, external kexts and the 64bit mode (snow leo only). DSDT override will be needed for the upcoming updates, otherwise osx86 systems will have kernel panic due to new RTC driver. "External kexts" option allows users to use external location for their special drivers (/Extra/Extensions), this will protect them from the updates. iATKOS v5i installation has all the needed scripts and packages for you to prepare an upgradable system and update like real Macs, but you need to read the information about preparing an upgradable system below.

The other choice is Chameleon v1.0.11. This is compatible for most systems, users whom want to have a normal old-style osx86 system may choose this bootloader. Decrypters: You must select one of the decrypters for your x86 hardware. SMBIOS: You need to select one of the enablers or classic x86 SMBIOS drivers. Enablers allow your system to run on stock SMBIOS driver and this is also a must for upgradable systems. x86 patched SMBIOS' are for normal old style osx86 systems. Kernel: You can choose 9.5.0 voodoo, 9.5.0 fassl kernel or old 9.2.0 toh kernel which is compatible for most.

For upgradable systems, the custom kernel you selected will be protected after applying the update, which means you will be running on new System.kext + your old 9.x.0 custom kernel which is not right. System must run on System.kext that belongs to your kernel version. So, you will need to replace new System.kext with your old System.kext, otherwise you will not able to use none of USB devices. You can find your custom kernel's System.kext under /Library/Temp. New updated one is in /System/Library/Extensions folder. Do not forget to repair the disk permissions using Disk Utility. If you want to switch to stock kernel when running upgradable system, then you need to edit com.apple.Boot.plist file under /Library/Preferences/SystemConfiguration. You need to change the value ''custom'' to ''mach_kernel'' and reboot. Don't forget to use the same System.kext version with your running kernel. For normal iATKOS osx86 systems you need to check /Library/Backups folder for the stock kernel and replace it with the existing kernel on your root. ACPI: Main system includes stock ACPI driver. You can choose modified ACPI for shutdown/reboot problems and also you can select OHR driver for such issues. You can choose x86 modified ACPI driver for PS2 mouse/keyboard and also PS2 driver can sure manage that but it is not a good choice for upgradable systems. You may need to select APIC driver for some mobo. Disabler: This driver disables some problematic drivers, you may not need this for PC_EFI V9 systems but this can still be usefull for most systems. Remove PowerManagement: This removes the most problematic driver. You do not need it if you select Disabler or if you are on PC_EFI V9 bootloader. PS/2: Driver for PS/2 keyboard/mouse. You will need to modify the Info.plist of ACPIPS2Nub.kext for the update's ACPI version before applying main system update, otherwise your ps2 mouse/keboard will not work. For upgradable systems, I advice you to use x86 ACPI driver instead of this. OHR: Driver for freeze issues on shutdown/reboot. Modified ACPI driver can be an alternative for this. Drivers: Additional drivers for your setup. Please read the descriptions.

What's OSx86? OSx86 is a project dedicated to run the Mac OS X operating system on non-Apple PCs that use x86 architecture processors. OSx86 has been made possible at June 2005, when the Worldwide Developers Conference announced that Apple transferred their personal computers from PowerPC to Intel Processors.

Where can I download iATKOS v5i? Search around the net and you'll find it.
